Raindrops on my umbrella

It has been quite mixed weather in Oslo today. It rained in the morning, then we had a few hours with beautiful sunshine. Then some thunder and lightning with heavy rain. And now the sun shines again. Kind of weird.
On my way to work I took a few pictures of my umbrella using my Canon G9 camera. I converted them to grayscale and then to duotone with a dark blue colour. There is another picture here.
